Nobody ever said it was a clone of any saw, because it is not. Yes, the top arm lifts, but when you release the tension the top clamp automatically realeses the blade, making it impossible to top feed. When you mount the blade to the top clamp, it clamps the blade and tensions the blade at the same time.There is a slot in the table to allow you to slip the blade and bottom clamp in which makes it easier to feed the blade from below, but not from above.
Like the Excaliburs, the head tilts instead of the table, but unlike the Excaliburs, it had a cast iron table.
It's a well built saw, they just left out any ability to top feed.
